When, how and where to watch the total lunar eclipse in India

Could the Moon have been seeded with life from Earth

The Guardian had reported that Nigeria and most other parts of the world would on July 27, 2018 experience blood moon- a spectacular total lunar eclipse.

The total eclipse lasted 1 hour, 42 minutes and 57 seconds, though a partial eclipse preceded and follows, meaning the moon will spend a total of almost 4 hours in the Earth's umbral shadow, according to NASA. A total lunar eclipse occurs when the sun, Earth and moon line up perfectly, casting Earth's shadow on the moon. This happens when the Earth passes between the Sun and the Moon.

That colour is due to sunlight leaking through Earth's atmosphere and reaching the Moon.

Hence a black shadow will be seen taking a bite out of the moon. A new paper was published online today (July 23) in the journal Astrobiology with a thrilling headline: "Was There An Early Habitability Window for Earth's Moon?" This will result in Mars coming close to the Earth, causing it to appear brighter than normal and it will be seen from evening to dawn towards the end of July. "Astrology is not something we follow". "Of course, the issue of shutter speed is always there; too slow an exposure and all we'll see is an unsightly lunar streak, even with a wide-angle lens".

However, the partial eclipse will be visible for nearly four hours.

"Totality will last for 103 minutes, making it the longest eclipse of the 21st century!" said the Royal Astronomical Society in London.

A few minutes after 8am on Saturday (NZ time) - and weather permitting - people in southern areas of the country should be able to view a rare celestial event called a selenelion.

"Meanwhile the greatest eclipse will be visible at 01-22 PST on July 28 which is going to be a historical moment", the PMD official said.

"The total lunar eclipse will be fully visible in Thiruvananthapuram".

There is no need to wear goggles or filters to watch a blood moon as is necessary with solar eclipses, it's completely safe to view with the naked eye. The Earth's shadow will cover the moon for an hour and 43 minutes.

Astronomer Dr Gregory Brown, from the Royal Observatory, Greenwich, explained: "At total eclipse, rather than turning black as you might expect, the Moon will turn a deep red as light from the Sun is bent onto it by the Earth's atmosphere, just like the lenses of a pair of glasses bend light into a person's eyes".

Another factor that is playing a role in the eclipse's duration is the path that the moon is taking through the Earth's shadow.

However, the drop in natural light pollution during the total lunar eclipse will allow people to see more of the dimmer meteors. "We've all caught on to this lovely word "blood-moon". "Not quite as bright as Venus, but still because of the reddish, orange-ish-red color, you really can't miss it in the sky".

Yes, they will. It will be best visible in the eastern regions of Ukraine.
